study of abexinostat in patients with relapsed or refractory follicular lymphoma

Conditions: Follicular Lymphoma

Summary: this study in patients with relapsed/refractory follicular lymphoma who have undergone at least 3 lines of therapy. patients will receive abexinostat 80 mg (4 × 20 mg tablets) twice a day (bid) in a "one week on, one week off" schedule.

patients will be evaluated for objective response, duration of response (dor), progression free survival (pfs), clinical benefit rate (cbr), overall survival (os), safety and tolerability, pharmacokinetic (pk), pharmacodynamic (pd), and changes in health related quality of life. patients may receive treatment until disease progression, death, unacceptable toxicity, or withdrawal of consent. an independent data safety monitoring committee (idmc) will evaluate the data pertaining to the futility and decide whether the study should stop or continue to the second stage. if the study continues to the second stage, a total of 139 patients will be studied.
